A monowheel is a one-wheeled vehicle similar to a unicycle. However, instead of sitting above the wheel, the rider sits either within it or next to it. The wheel is a ring, usually driven by smaller wheels pressing against its inner rim. Most are single-passenger vehicles, though multi-passenger models have been built.
Pedal-powered monowheels were built in the late 19th century; most built in the 20th century have been motorized. Some modern builders refer to these vehicles as monocycles, though that term is also sometimes used to describe motorized unicycles.
Today, monowheels are generally built and used for fun and entertainment purposes, though from the 1860s through to the 1930s, they were proposed for use as serious transportation.

Variants and related vehicles
There have been many proposals for variants or uses, such as a horse-drawn monowheel or a monowheel tank or Philip Beltracchi's mousetrap powered monowheel. A variant was proposed that placed two riders outside of the wheel itself, with one person on each side to provide for balance.
One interesting variant presented at Burning Man in 2003 involves the passengers sitting in front of the wheel and being balanced by a heavy counterweight inside the wheel. Rather than the typical ring drive, this vehicle is powered through a sprocket attached to the spokes.
A related vehicle is the diwheel or the dicycle, in which the rider is suspended between or inside of a pair of large wheels placed side by side. An example of this would be the character Axel from the Twisted Metal series of video games published by Sony.
